Elections seem to spit out endless data, but you need to find the right angle and do it at speed, which explains why in this election we chose to focus on the candidate that came third

The first European election of 2021 was the vote for the Portuguese executive head of state. It was no surprise that among the seven candidates fighting for the vote, the victor was the incumbent 72 year-old Marcelo Rebelo de Sousa of the Social Democratic Party. However, the data-viz story here isn’t in who won, but in the worrying success of the Far-Right candidate that came third.

Find the right angle to pursue

We found out which cities took longer than others to stop commuting in response to the coronavirus pandemic

Coronavirus has had an incredible impact on the way we live our lives. To contain the spread of the virus, many governments have prohibited us from visiting friends and family or travelling to workplaces, shops and restaurants. Commuting in cities across the world has ground to a halt.

One way which we know that this has happened is because users of apps like Citymapper have stopped using them to plan journeys.

Parasite makes history winning Best Picture, but it also confirms a new trend in the foreign language category

Last year for the Oscar season we crunched the data of which Oscar nominations make a Best Picture win more likely, as well tracking the success of films with strong female performances against those with just male acting nominations.

This year with all the buzz about the South Korean movie Parasite, we took a closer look at the Foreign Language Oscar category data. Below is a data viz, created by my partner João Silva and I, which I will briefly comment on in two parts.

We created an interactive data viz tool to compare tennis success by country

Statistics from the Grand Slam tennis competitions give ammo to no end of data stories. From looking at the success of nations over time; the differences between the men’s and women’s game; to comparisons between the four different competitions.

We created this tool to make it easier to get our teeth into the mass of data available on the Grand Slams — just in time for Wimbledon.

First, how to use our tool ‘Grand Slam Stats’

It’s simple to create your own chart to explore the data. Follow the link above and then pick from this range of options:

  • women’s or…

London just celebrated Pride, but what can the data tell us about the different views of heterosexuals and LGBTQ Londoners?

The UK is rated as a ‘gay-friendly’ country, coming nine out of 49 European countries in ILGA-Europe’s ranking and 16th in Spartacus Gay Travel’s world index. Within the UK, London has the biggest LGBTQ community and is often seen as its most LGBTQ progressive city above Brighton and Manchester.

But the lived experience of members of the LGBTQ community can tell a different story. Reports of hate crimes are increasing and a recent Stonewall report found that 25% of London’s LGBT community had experienced harassment or assault.

I used the results from a survey that was released a few days…

Using data visualisation to take a closer look at voting patterns, strategic voting and LGBTQ rights in Eurovision countries

Due to the sheer volume of statistics that it spits out each year, Eurovision is a dream come true for creating data visualisation — especially for superfans like myself and Joao.

In anticipation of tonight’s final, we’ve looked at which nations have chosen the winner the most times; who are Europe’s best friends in terms of voting; and whether gay-friendly countries are actually the bigger fans?

Which country ‘chooses’ the winner?

Despite not securing a win for decades, it is the UK that has given its maximum points to the contest’s winner…

Films with only strong women do worse and the four nominations that make a Best Picture Oscar more likely.

My partner and I are massive fans of the Oscars and we also love to dabble in data visualisation — last year we won third prize in a competition using charity data. So with the Oscars tonight, now is the time to turn our attention to the Olympics of the movie world.

Just like everyone else, the question we want to answer is which Best Picture nomination is most likely to win, and whether there is some kind of formula for predicting it.

The magic four nominations

We looked at the Best Picture winners from the past 90 years and analysed the number of…

On Sunday I’ll run my eleventh marathon outside of my home country — in Sapporo, Japan. It’s a great way to combine running and travel, so here’s three reasons why your next marathon, half or 10k should be international.

A reason to travel

Everyone loves a holiday, so give yourself a reason to deserve one. A marathon can easily fit into a cheap city break. There is also a range of adventure races if you are feeling bold — the Great Wall of China, during the Tromsø Midnight Sun or even a marathon with 23 wine stops.


I recently travelled through Vietnam, one of the 12 million tourists that visit each year. Whilst this number will include those with a connection to the War, as well as history geeks that have studied it like me, most will know little about one of the most important events of the 20th century.

‘The American War’, as its known to the Vietnamese, was a Cold War conflict occurring from 1955 to 1975. Estimates of Vietnamese casualties range from 1m to 3.8m with terrible atrocities committed…

New Zealand is without a doubt a wonderful country—with some of the most beautiful views and friendliest people I’ve ever come across. But it is also a country with a severe mental health crisis.

During my three months travelling up and down New Zealand, I also had the opportunity to speak to people from its mental health sector and learn more about an issue close to my heart. In several ways, mental health initiatives are well advanced on this side of the world, but here are three observations on it’s mental health crisis and how it compares to the UK:
